Erythrite and annabergite (Ni3(AsO4)28H2O) (nickel arsenate) form a complete series with the general formula (Co,Ni)3(AsO4)28H2O. Erythrite crystallizes in the monoclinic system and forms prismatic crystals. The color is crimson to pink and occurs as a secondary coating known as cobalt bloom on cobalt arsenide minerals. Well formed crystals are
